2: KEYPAD FUNCTIONS

ON/OFF

Turns the gauge on and off. When pressing the ON/OFF key while in the off position, gauge start-up display first indicates the software version followed by the model number and gauge pressure range. The gauge will then display indicated pressure and be ready for use.

ZERO

CLR

Press this key for one second prior to gauge usage to re-zero any initial zero shift. If zero shift is greater than programmed zero allowance, the gauge will display

Ofset

(blinking) for one second, then return to the measure mode. To clear minimum and maximum values, press

ZERO/CLR

button (when min/max values are indicated). Gauge will auto advance once zeroed.

MAX/ MIN

The

MAX/MIN

key allows review of minimum and maximum pressure values since unit star-up or last push of the clear key. Press key to:

1) Indicate maximum pressure.

2) Indicate minimum pressure.

3) Exit

MAX/MIN

mode and return the unit to pressure measurement mode. To clear minimum and maximum values press

ZERO/CLR

key (must be in

MAX/MIN

mode).

The (down arrow key) is used in the

MENU

mode; see following

MENU

section.

MENU

This key allows for customization of the gauge. Pressing the

MENU

key allows cycling through the main

MENU

items:

UNITS, CONFIG, GRAPH, OFF, UPDAT

&

DAMP.

Any item changed in the

MENU

becomes the new default setting(s). Revised settings are saved in the event of power loss.

The (up arrow key) or (down arrow key) on the keypad allows for scrolling through the

MENU

options to increase or decrease numeric values as required. If in the

MENU

mode, gauge will automatically advance to measure mode once selected

MENU

item has been set.

CONFIG

mode is required, the user will be prompted to

ENTPW

(or “enter password”).

Follow steps 4-8 above.

RECAL

(or “recalibrate”)

:

Allows for zero, mid-scale, full-scale and factory default calibration of the gauge. The

RECAL

feature also allows for recalibration of gauges with 4-20mA output.

To use the RECAL option:

Step 1:

Press the

MENU

key on the keypad.

Step 2:

Press the (up arrow key) or (down arrow key) on the keypad until the word

CONFIG

appears.

Step 3:

Press

ENTER.

Step 4:

Enter user password if it has been programmed.

Step 5:

Press the (up arrow key) or (down arrow key) until the word

RECAL

appears.

Step 6:

Press

ENTER

Step 7:

The gauge will now flash between

INPUT

and unit of measure on the lower line and .00 on the top line. Apply zero pressure to the gauge.

Step 8:

Press

ENTER.

Zero pressure is now set.

Step 9:

The gauge will display full-scale pressure. Apply full scale pressure to the gauge.

Step 10:

Press

ENTER.

Full scale pressure is now set.

Step 11:

The gauge will now display mid-scale pressure. Apply mid-scale pressure to the gauge.

Step 12:

Press

ENTER.

Mid-scale pressure is now set.

Note: For compound ranges this will be full vac.

FOR FACTORY CALIBRATED SETTINGS:

Step 15:

After zero, full-scale and/or mid-scale or factory default calibration have been set, the word

(down arrow key)

MENU

key until the word

FACT

appears.

Step 14:

Press

ENTER.

Factory calibration settings are now reinstated.

Note: Calibration of Zero, mid-scale or span can be set independently of each other. For instance, if only half scale calibration is required, press the (down arrow key) until the gauge indicates full-scale pressure. Press ENTER and proceed as indicated above. Calibration of zero, mid-scale and full-scale is recommended when recalibrating the gauge.

ZERO KEY (ObUTN):

This feature allows the user to select percent of full-scale at which the gauge can be re-zeroed using the

ZERO/CLEAR

key on the keypad. Options include:

10% FULL-SCALE

or

ENTER

to finalize the selection.

GRAPH:

This option allows the user to change the

BAR

graph on the gauge display to correspond to any desired pressure within the pressure limits of the gauge. This option is useful when identifying a select portion of the full-scale range of the gauge. The default setting of the

GRAPH

is zero and full scale pressure. For compound gauges, the default setting for zero is set at full-scale vacuum.

Full-scale pressure is set at the positive pressure as displayed on the gauge keypad.

For gauges supplied with the 4-20mA output option, the default is 4mA equals 0% of the bar graph and 20 mA equals 100% of the bar graph.

Note: Changing the graph to a pressure other than 0 and 100% of range will also change the4-20 mA output to correspond with the new bar graph pressures for 0 and 100%.

To use GRAPH option:

Step 1:

Press the

MENU

key on the keypad.

Step 2:

Press the (up arrow key) or (down arrow key) on the keypad until the word

GRAPH

appears.

Step 3:

DAMP

(or “dampening”): This mode has five different options. This mode allows for taking process pressure readings and averaging them. This option is particularly useful to stabilize minor process fluctuations. The options are:

NONE

*

To use the DAMP option:

,

AVG 8, AVG 6, AVG 4

and

AVG 2.

Step 1:

option

(The following MENU item is only seen on units with the switch option.)

SWSET:

Allows for setting switch set-points. The gauge is offered with one or two

SPDT

switches. If

1 (one)

SPDT

switch is ordered the

MENU

option is

SW1.

if 2 (two)

SPDT

switches are ordered, the

MENU

options are

SW1

and

SW2.

21-11-1508 Page 8

! "

To use the SWSET OPTION:

Step 1:

Press the

MENU

key.

Step 2:

Press the (up arrow key) or (down arrow key) on the keypad to select the switch to be set (if two switches are present).

Step 3:

Press

ENTER.

The top line of the gauge display will indicate pressure at

60% OF

THE FULL-SCALE GAUGE RANGE

*

or the

MOST RECENT SWITCH SET-

POINT

. The middle line of the disposition will indicate a bar graph that displays the pressure position within the pressure range. The bottom line will display

SETPT

(blinking).

Note: Set-points are limited to the full-scale pressure range of the gauge.

Step 4:

Press the (up arrow key) or (down arrow key) on the keypad to increase or decrease switch set-point.

Step 5:

Press

ENTER

to finalize the switch set-point. The gauge will display

SET.

After two seconds the top line will indicate

RETRP

pressure. The bottom line will read

SET.

STEP 6:

Repeat the above steps to set

RETRP

(re-trip value). If the gauge is supplied with 1 (one) set-point, the screen will advance to the measurement mode. If 2

(two) switches are supplied, the screen will advance to

SW2.

Repeat the aforementioned if the gauge is supplied with two switches.

Note: The bar graph will increase or decrease as any set-point pressure is adjusted.

The bar graph indicates switch set-point position within the full-scale range of the gauge.

The switch set-point unit of pressure measurement corresponds with the current set unit of measure of the gauge. If gauge unit of measurement is changed after switch (es) is/are set, switch set-point(s) will automatically be updated to correspond with revised unit of measurement. Switch dead-band is the difference between the SETPT (set-point) and the RETRP (re-trip) pressure.

3: Battery Replacement

3” Gauge:

The 3” gauge case uses a quantity of 2—AA alkaline batteries. Approximate battery life is 1500 hours. The gauge has approximately 7 hours of use left, when the lower bar flashes on the battery icon.

Replacement:

Step 1:

Remove the single screw on the back of the case.

Step 2:

Hold the keypad in hand.

Step 3:

Carefully remove the two batteries from the holder, and replace with new.

Use only AA Alkaline Non-Rechargeable batteries.

4.5” Gauge:

The 4.5” gauge uses a quantity of 2 C Batteries. Use only Alkaline, Non-Rechargeable batteries. Approximate battery life is 3600 hours. The gauge has approximately 7 hours of use left, when the lower bar flashes on the battery icon.

Replacement:

Step 1:

Remove the ring on the front of the gauge case.

Step 2:

Carefully pull the front face out of the case.

Step 3:

Carefully remove the 2 batteries and replace them.

General Notes for both gauges:

1) Never replace only one battery.

2) Do not mix ages or brands of batteries.

3) Do not replace batteries in hazardous areas.
